Charter School Lottery Statistics

Mid-April marks the beginning of the charter school lottery season, and with it, news reports of staggering numbers of applications to schools with limited slots. Already, the Post reported that 3,800 students applied for 588 spots in the Achievement First charter schools. In order to review the results for past lotteries, I submitted a Freedom of Information Law (FOIL) request to the State Education department, who provided us with the Basic Education Data System (BEDS) data that all charters file with the state. I found that applications to charter schools have increased by 50% since 2007, with over 50,000 applications submitted last year. By comparison, enrollment in charters has only increased by 40% to just shy of 40,000 students last year. The chances of getting admitted to a charter school in New York City have declined from an average acceptance rate of 36% in 2008-2009 to a rate of 28% in 2009-2010. A full spreadsheet of the admissions data, with statistics for individual schools, is available here.

To be clear, these numbers only tell part of the story. They do not, for instance, take into account double counting—i.e. the fact that many parents apply to multiple lotteries.  Nor do they offer detailed information about where these applicants live, so it is hard to say if charters get many applicants from far away districts or from close to the school. In fact, charter operators are instructed NOT to list the district numbers of their students on the BEDS form, despite the fact that the information could be easily collected. Despite the drawbacks, this data does offer insights into where applications are the most numerous—and how the number of applications correlates to things like age of the school and its Progress Report score. The 11 schools that had admissions percentages of less than 10% last year were*:

1. Bronx Charter School for Better Learning
2. Bronx Charter School for Children
3. Bronx Charter School for Excellence
4. Community Partnership Charter School
5. Community Roots Charter School
6. Future Leaders Institute Charter School
7. Grand Concourse Academy Charter School
8. Icahn Charter School 1
9. Merrick Academy/Queens Public Charter School
10. Renaissance Charter School
11. The UFT Charter School

I found that schools that have been in operation longer generally have lower admissions percentages—and this is a trend that has increased in recent years. Schools such as the Sisulu-Walker Charter School, Renaissance Charter School, and Grand Concourse Academy, all of whom have been open since at least 2004, have had admissions percentages below 15% for the past three years. There appears to be no correlation between Progress Report scores and admission numbers in the following year. Indeed, out of the 19 new charter schools opened in 2009-2010 (for which no scores yet exist) 15 had admissions percentages of less than 50%.

I also looked at admissions to charter schools based on neighborhood. I focused on Central Brooklyn, Harlem, and the South Bronx, as they are the areas that have the most charter schools. It has actually gotten easier to be admitted to a charter school in the South Bronx, where approximately 1 in 3 applicants is offered a spot. In Harlem, however, the chances of admittance have plummeted: in 2007-2008, the rate was 40%. Last year, it was 18%.

In future posts, I will be looking at the BEDS data related to suspensions, class size, and pupil retention. As always, I welcome comments and suggestions for ways to improve my calculations.

*I am leaving out the four Harlem Success Academy schools that were open in 2009-2010 because it is unclear whether the numbers refer to each individual school or all four schools. I will update when I have better information.

Looks like that before long, getting in a charter school will be as daunting a task as winning the lotto!

Ever wonder why you can't win the lotto while others have won more than once? http://www.classyscripts.com/go.php/lotto/

Hello
A lottery is a form of gambling which involves the drawing of lots for a prize.Lottery is outlawed by some governments, while others endorse it to the extent of organizing a national or state lottery. It is common to find some degree of regulation of lottery by governments. At the beginning of the 20th century, most forms of gambling, including lotteries and sweepstakes, were illegal in many countries, including the U.S.A. and most of Europe.

As for the data themselves, I would like to know more about your purposes for this data display, and your intended audience before suggesting other bits of information to add.
